Cortex uses a small vocabulary consistently, and most of it is ordinary English used precisely. This page collects the words you will meet on other pages of this site, in alphabetical order, with one or two sentences each and a link to the page that explains the thing properly. Only words the product actually uses are listed here. The application names themselves are not in the list: Cortex Chat, Cortex Code, Cortex Bot, Cortex Design, Cortex Security, the Cortex CLI and Cortex Bounty each have their own section of the site. ## A to C | Term | What it means | | ------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Activity** | The record of what happened on your account across Chat, Code and Bot, covering sign-ins, connector changes, exports and approvals over the last 30 days. See [Data and privacy](/getting-started/data-and-privacy). | | **Appshots** | A desktop-only capture of the last Chat or Code thread you used, taken with a double tap of a modifier key. The web app has no global hotkey. See [Cortex desktop app](/getting-started/desktop). | | **Approval matrix** | The grid in **Settings** where you choose **Ask** or **Always ask** for each kind of action, read, edit, shell and pay, on Chat, Code and Bot. Pay always asks. See [Permissions and approvals](/code/approvals). | | **Artifact** | Something Cortex produced that is kept in its own place rather than only inside a transcript. The sidebar collects them under **Artifacts**. | | **Canvas** | A document surface you keep and work on, rather than a message in a conversation. Chat and Cortex Design each have their own. See [Chat canvases](/chat/canvases) and [Design canvases](/design/canvases). | | **Closed beta** | A product that is open only to invited accounts. A signed-in account that has not been invited sees a gate and can continue in Chat. See [Accounts and sign-in](/getting-started/accounts). | | **Command palette** | The jump-anywhere panel in Cortex Code, opened with `⌘ K` or `Ctrl K`. See [Keyboard shortcuts](/getting-started/keyboard-shortcuts). | | **Connector** | A connected app whose tools join your conversations, so Cortex can act on that app instead of only talking about it. See [Connectors](/chat/plugins). | ## E to M | Term | What it means | | -------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Entitlement** | A capability that a plan includes. When your plan does not include one, Cortex says **Not included in your plan**. See [entitlement\_required](/problems/entitlement_required). | | **Global Privacy Control** | A signal some browsers send to refuse optional tracking. Cortex honours it: optional analytics stay off and the signal wins over an "allow" sent from the page. See [Data and privacy](/getting-started/data-and-privacy). | | **Grace period** | The 30 days between requesting deletion of your data and the erasure actually running. Signing in again during that time cancels the request. See [Data and privacy](/getting-started/data-and-privacy). | | **Guest** | Someone using Chat without signing in. A guest has a message allowance for the browser session and cannot create anything it would later need to come back and revoke. See [Accounts and sign-in](/getting-started/accounts). | | **Library** | Where Chat keeps the files you upload and the files it produces. The storage meter under **Plan & billing** measures it. See [Library](/chat/library). | | **Mascot** | Another word the product uses for a bot, most visibly when Cortex asks whether your mascots may use your connected tools. See [Cortex Bot](/bot). | | **MCP server** | A Model Context Protocol server you attach over HTTP so its tools join the model in your conversations. See [MCP servers](/chat/mcp-servers). | | **Member** | A signed-in Cortex account. Everything beyond guest Chat is member territory. See [Accounts and sign-in](/getting-started/accounts). | | **Memory** | Standing preferences and facts you have shared, kept so answers get more personal over time. Reviewable, deletable, and switchable off. See [Memory](/chat/memory). | | **Mode** | Chat, Code and Bot are modes of one shell. Switching mode keeps the shell and the sidebar in place rather than loading a different application. See [What is Cortex](/getting-started/what-is-cortex). | ## O to R | Term | What it means | | ------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Overlay** | A dialog that opens over the product instead of navigating away from it. Settings is the one you meet most. See [Settings](/getting-started/settings). | | **Plan** | The named ceiling on what an account may use in a window. The ladder is Guest, Free, Go, Plus and Pro. See [Plans and quotas](/getting-started/plans). | | **Preview** | A label on a live model whose name and behaviour are not final. Every public Cortex model carries it today. See [Models](/reference/models). | | **Problem code** | The stable identifier attached to every failure, such as `quota_exceeded` or `forbidden`. Each one has its own page. See the [problem catalog](/problems). | | **Project** | A container for related chats and files, with custom instructions of its own that can override your account instructions. Your plan caps how many you may have. See [Projects](/chat/projects). | | **Quota** | A count that resets on a fixed window, such as messages today or messages this month. See [Limits and quotas](/reference/limits). | | **Reference id** | The identifier printed on a failure card. Quote it in a bug report and the team can find the exact request. See [Errors](/reference/errors). | | **Reserved space** | A member-only product that a guest has opened. The dialog offers to sign you in, or to continue in Chat. See [Accounts and sign-in](/getting-started/accounts). | | **Routine** | A repeatable job you set up in Cortex Bot. Routines belong to your account and follow you across devices. See [Routines](/bot/routines). | | **Runtime** | The isolated computer a Cortex Code session runs in. See [Cloud runtimes](/code/runtimes). | ## S to W | Term | What it means | | ------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | **Scheduled task** | A Chat task that runs on a schedule rather than when you ask. Cortex notifies you after one has run. See [Scheduled tasks](/chat/scheduled-tasks). | | **Session** | A unit of work in Cortex Code, started with **New session** and kept as its own thread of changes. See [Code sessions](/code/sessions). | | **Shortcut sheet** | The in-product list of keyboard chords, opened and closed with `⌘ /` or `Ctrl /`. It lists only chords that are actually bound. See [Keyboard shortcuts](/getting-started/keyboard-shortcuts). | | **Single sign-on (SSO)** | Signing in through your organisation's identity provider instead of a personal account. See [Accounts and sign-in](/getting-started/accounts). | | **Skill** | A reusable capability you add to a product. Chat, Cortex Bot and the CLI each document their own: [Skills in Chat](/chat/skills), [Bot skills](/bot/skills), [Skills in the CLI](/cli/skills). | | **Step-up confirmation** | Re-entering your authenticator code before a sensitive action such as an export or a deletion. A confirmation lasts fifteen minutes and covers only the session that asked for it. See [Two-factor authentication](/getting-started/two-factor). | | **Temporary chat** | A conversation that neither reads nor writes memory. See [Conversations](/chat/conversations). | | **Window** | The period a quota counts over, a day or thirty days. Windows are fixed rather than rolling, and the product shows a **Resets in** line instead of a wall-clock time. See [Plans and quotas](/getting-started/plans). | ## Words that belong to one product Some vocabulary is specific enough that it is defined where it is used rather than here: tickets and environments in Cortex Code, channels and tasks in Cortex Bot, checks and review policy in Cortex Security, and hooks, agents and themes in the Cortex CLI. Each product's own pages carry those definitions, and the [Related](#related) links below are the fastest way in. ## Related * [What is Cortex](/getting-started/what-is-cortex) for the applications and how they fit together. * [Which product do I need?](/getting-started/choose-a-product) for picking one. * [Plans and quotas](/getting-started/plans) for plans, quotas and windows. * [Frequently asked questions](/getting-started/faq) for the short answers. * [Troubleshooting](/getting-started/troubleshooting) for what a message in the product means.
